Frequently asked
Which state has the highest claim denial rate?
Click any state on the map or in the state list to see its ranked insurers. Darker states on the map have insurers that deny claims more often.
Why do denial rates vary by state?
Each state has a different mix of insurers, plan designs, and health systems, so the same insurer can deny at different rates in different markets.
Does this include state-run marketplaces?
No. Covered California, New York State of Health and other state-based marketplaces do not report to the CMS Transparency in Coverage file. HealthCare.gov states only.
How recent is the state data?
Claims years run through 2024, computed from insurers' CMS Transparency in Coverage filings.
